Control key functions
[display / status] is used for selecting the mode of
display or for changing back to Display mode from
either the Quick menu mode or the Menu mode.
[quick menu] is used for programming the param-
eters that belong under the Quick menu mode. It
is possible to switch directly between Quick menu
mode and Menu mode.
[menu] is used for programming all parameters. It is
possible to switch directly between Menu mode and
Quick menu mode.
[change data] is used for changing the parameter
selected either in the Menu mode or the Quick
menu mode.
[cancel] is used if a change of the selected
parameter is not to be carried out.
[ok] is used for confirming a change of the
parameter selected.
[+/-] is used for selecting parameter and for
changing the chosen parameter or for changing the
read out in line 2.
[<>] is used for selecting group and to move the
cursor when changing numerical parameters.
[stop / reset] is used for stopping or for resetting
the pump after a drop-out (trip). Can be selected
via parameter 014 to be active or inactive. If stop is
activated, line 2 will flash, and [start] must
be activated.
attention:
Pressing [stop/reset] will prevent the pump from running also
with disconnected lcp. Restarting is only possible via the lcp
[start] key.
[jog] overrides the output frequency to a preset
frequency while the key is kept down. Can be
selected via parameter 015 to be active or inactive.
[fwd / rev] changes the direction of rotation of the
motor, which is indicated by means of the arrow on
the display although only in Local. This key is
inactive by default.
[start] is used for starting the pump after stop via
the [stop] key. Is always active, but cannot override
a stop command given via the terminal strip.
6.1.4 display mode
In normal operation, up to 4 dierent operating variables can be
indicated continuously: 1,1 and 1,2 and 1,3 and 2, and in line 4 the
present operating status or alarms and warnings that have arisen.
There are three options in connection with the choice of read
-out state in the Display mode - I, II and III. The choice of read-
out state determines the number of operating variables read out.
